Claims priority, application France February 12, 1951 Claims. (Cl.1197-177) The increasing complexity of economic problems inadministrative work requires the use of highly improved calculatingmachines in order to accomplish statistics, accounting operations andthe like.

The present invention concerns an improvement in mechanical elements incalculating machines presenting a great number of totalisers which aredesigned for accounting and statistical analysis and according to themachine described in U. S. Patent No. 2,562,172, dated uly 3l, 1951.This machine is essentially characterized in that it comprises a certainnumber or counting units respectively representing an account or entry,each of which is formed of a linkage composed of rods or slides whichare shiftable in a longitudinal direciton and are provided, lengthwise,with catches or teeth, the number of which equals the number of units,less one, of the adopted basis oi numeration and which materialize thecalculating elements, each linkage bearing such rods or slides in anumber equal to the number of numeration orders foreseen for thecalculations to be accomplished; mechanical means cooperating with theVcatches or teeth of said rods or slides, in order that one or moredetermined counting units may automatically impart to the rods orslides, under the action of an electrical or any other motor and underthe control of a keyboard comprising groups of keys corresponding to thevarious counting units and groups of calculating keys, frontward orbackward movements proportional to the numbers represented by thecalculating keys which are acted upon by the operator; and mechanicalmeans in connection with said rods or slides in order that the recordingor printing of the data of the operations and their results be insured.

En such machines, the control of tabulations in both direcitons isperformed in various known ways and generally by means of theaccumulated force in a clock spring. This evidently provides someautomatic features in the tabulating control.

On the contrary, the present machine provides an imperative controldevice for tabulating in both directions by means of an electric motorcontrolled by a clutching and unclutching device substantiallycomprising a plate fast with a trame and provided with a shaft aroundwhich rotates a pinion driven by two toothed wheels cooperating in areverse direction one with the other, mounted on sockets fast with saidplate and each provided with two triggers rotatively arranged in notchesprovided in the body of said wheels perpendicularly to their plane ofrotation, a second plate connected through struts to the rst plate, tworatchets cooperating with the wheel driving the tabulating bar, twoshafts sliding inside said sockets and provided with washers enteringgrooves provided at the end of the triggers and the sliding position ofwhich enables the triggers to cooperate with the corresponding ratchet,a third plate connected to the second plate through struts and providedwith horizontal bearings in which may rock a shaft and a Patented Jan.i5, 'i957 ice mine the direction of rotation of the wheel driving thedisplacement of the carrier.

Said rocking member is maintained in its position by means of rollersarranged in conical holes provided in the plate which corresponds to it.The length of the noses of the triggers may be calculated in order that,eX- cept for the two extreme positions, none of the triggers maycooperate with any of the ratchets for an oblique position of saidrocking member thus allowing both toothed Wheels to be driven, withoutthis driving being communicated to the wheelV drivingvthe carrier. Theplate provided with horizontal bearings at the height of whichoscillates the member in the form of a rocking device is fast with aplate on which are arranged two locks capable, on the one hand, ofsliding lengthwise and, on the other, of slightly shifting around twoshafts fast with a plate connected by means of struts to a cover on theinside face of which are rotatively arranged two levers, one rounded endof which enters a groove provided in said locks, whereas two otherlevers, rotatively arranged on said plate, also exert a pressure on saidlocks in order to provide a guide for the locks in their lengthwisemovmcent. n

in case the amplitude of the movement of the rocking member is too greatand in order to avoid a reclutching of the carrier, after an unclutchingaction, levers are rotatively arranged on the plate fast with said coverand provided at their ends with weights to damp the rocking movement dueto toov fast an unclutching action.

The machine as shown Ycomprises a frame formed of a Vbottom plate 1 fastwith two right and leftV flanges 2 and 3', connected by square struts 4,5, 6 and 7, and an intermediary ange 8 maintained by said square struts6 and 7. On s aid frame are fixed all 'the mechanical elements of themachine, which'are hereafterV described.V g The machine comprises (Figs.1,v 1a and 5) two counting sections A1 and A2, each including a certainnumber which areV provided with studs 11 and 111, such as de-V ofcounting units, said sections being hereafter called ,y

scribed in my above mentioned, U. S. Patent 2,562,172.

- Said studs 11 and 111 act as guides for slides V12. Triangles 13and131 are guided by means of another group of cross-bars 9 and 91,arranged so as to cooperate with j other studs`14, also Vprovided onbars Y and 161, and [which may thus easily be shifted longitudinally.`

Springs 64 and 641 maintain bars 10 and 101 by pressing upon them (Fig.5) so as to lock'slides 12 by means of locking angle-barsv65 and 651.Said locking action continues as long as the corresponding counting unithas not been selected. Y Y `Two shafts 16 and 161 are mounted inupprrplates 17 f and 171 and lower plates 18 and 181 which are heldVparallel kby means of sleeves 19 and 191 (Figs. Vl, 1a andV 4). v Y

f `Y The unit thus constituted mayV rock around trunnions 20 and 201(Figs. l and la) xedl on plate 1. Y

Pinions 21 and 211 are fixed on shafts 16 and 161 (Fig. 20) andcooperate with racltsV 22 and 221 mounted on Y the upper bearings 17 and171, in order to drive a longi- 1 tudinal slide.

TheseV racks are permanently drawn towards the front of the machineby-.springs 164 and 1641, Y

maintained in position towards the front of `the machine yby a cross-bar30 (Figs. 1 and la) ixed at both its ends Vto `two parallel bars 31 and311, respectively sliding on the left and right hand anges of themachine. Bars 31 and 3,11 acted upon by springs 163 are maintainedtowardsV the front of the machine. by rollers 32 and 321 and levers V33and 331 (Figs. l, 1a, 2 and 2a). Said levers 33 and 311 Y are fastwithta Vshaft 34, Vone arm 35 of which is driven by a rod 35, a lever 37and a cam 38.l Cam 38 is fast with a shaft 39 rotated by the motor M ofthe machine, by

means of well known self clutching and unclutching system E, such as,for example, that described in my above mentioned U. S. Patent No.2,562,172, and visiblein Fig. 2. Lever 37 is rotatively mounted on Vashaft 40, the endsof which are Xed to flanges 2 and to the intermediaryange 8 (Figs. 1 and la). Shaft 39 is also rotatively mounted on saidanges 2 and 8.

Sliding barsv 31 and 311, Vin addition to the cross-bar 30 hereabovementioned, are provided with angle bars 167 and 1671 carrying springsstops 66Yaud 661,0ne for each numeration order, the functions of saidstops being hereafter explained.

Bars 31 are provided with slopes 168 and 1631 (Figs. l and 1a) forming asalient'on said bars 31.V These slopes rise during the returnmovement ofthe `bars 31 from the front towards the back of the machine.

Said bars 31 are furthermore provided with levers 169 and 1691 whichcontrol the rocking of levers 170 and 1761 which are respectively fastwith shafts 171 and 1711, which travel across the whole vwidth of themachine and are provided with ngers 172 and 1721 (Figs. 9 and 1l), theoperation of which is hereafter explained.

Levers 169 and 1691 4and shafts 171 and 1711 are rottivelym'ountedraround bearings fixed `on plate-shaped guides 191 and 11111,102 and 1021 (Figs. 2 and 2a). 0n an extension of plates 17 --and 171are mounted rollers '41 and' 411 on the axle of which are hooked springs42 and 421 xed, at their other ends, on slides 43 and 431, in Iorder tomaintain rollers 41 and 411 in contact with bent arms `44 and 441 -fastwith slides 43 and 431 (Fig. 20). VSaid slides43 and 431 are slidablymounted on bar 45,'which is alsoslidably mounted on-flange 2. Springs-46 and 461 are hooked yat one of their ends on ianges 2 and at theirother ends to slides 43 and `431. A'lever 4S maintains bar 45 rearwards,said bar acting against springs 46 and 461 by means of a rollerr47 xedonto said bar 45. Lever 48 (Fig. 3) is rotatively mounted on shaft 4)and providedwi-th a roller 49 driven by a cam fast with shaft 39. Shafts52 and 521 are rotatively mounted on supports 51'and 511 and areprovidedV with arms 53 and 531 which are for lthe purpose of locking thelower plates 18 and 131 in one direction or in the other yby actingonthe noses 181) and 181|of said bearings, either when said bearings 18and 181 are under ythe action of springs 46V and 461 yor when saidbearings 13 and 181 are under the action of springs 42 and 421' (Figs.1,V 111,3, 4, and 20), according to the position of cam 50 whichdetermines whether or not lever 48 will displace bar 45 submitted to theaction of springs 46 and 461. Shafts 5:72 and S21 are moreover fast witharms 54 and 541, carrying rollers 55 and 551 arrangedfor cooperationwith slidingbars 56, V57', 68, 69 (Figs. 10, 4 and 6) mounted on guides57 and 571 solid with plate 1. t

Bar 56 is maintained in its position towards .therear of the machine bymeans of a stop 59 driven by a spring 58V and said bar 56 tends to slidetowards Ithe front of themachine under the eioxtf of a roller 6i?carried by a lever 61 rotatively mounted on shaft 4Q and having an upperarm 62 provided with a nose capable V-of cooperating alternatively with'teeth '631 and 6310i a vearn 63 fast ywith shaft 39 (Fig. 6). t v

Bars V61, 68, 69 also slide on guides 67 and j671 and yare'drawnrearwards by means of springs 70, 7-1 anw;i 72. Bars 67 yand 68 are eachprovided, at one of theirends, with two shiftable levers 73,74 and 731,741 (Figs. -6 and 4) whereas bar 691s providedwith'onlyjone shift-ablelever 7,5. All these levers are pulled upwards by means of springs 76.These different levers'are `of an identical all levers 73 731, 74, 741and 75 (Fig. Y20) said levers being otherwise under the acti-on ofspring 76.

A sliding plate 82 (Figs. 4 and 20) is capable of sliding along a guide83 and is under the action of a spring 84 which causes the sliding plateto be pulled towards the right hand side of the machine.

A groove 85 is provided in plate 82 in order that only yone nose 66 ofone of the levers 73 to 75 may pass through plate S2, according to thesliding position of said plate. On the same guide S3 is rotativelymounted a lever 37 provided with a roller 8S entering a suit-able grooveprovided in plate S2. The other arm of said lever 37 is provided with asecond roller S9 which cooperates with the extension 90 of stop `bar 91(Figs. 4 and 8).

4Said stop bar 91 cooperates, in the manner described in my abovementioned U. S. Paten-t No. 2,562,172, with a group of keys 921 to 92e;stop bars 2S and 281 (Fig. 8) also respectively cooperate with two othergroups of keys, 931 to 939 (Figs. l and la). The above described membersare the control members for selecting the counters of each section andthe selection of functions will be described hereinafter with moredetails by the explanation of their operation as follows:

The operator depresses one of keys 931 to 939 (Figs. l and la) and thecounting unit of the corresponding section bearing the number of the keywill be caused to operate, when the motor is started, vshaft 39 beingdriven by the self clutching and unclutching device.

1n considering Figure 3, it may be seen that cam 50, fast with shaft 39,will exert a pressure upon roller 49, thus causing lever 43 -to rock,which lever will, in turn,

exert a pressure upon roller 47, causing bar 45 to slide -towards therear of the machine,lsaid bar being under the action of springs 46 `and461, on the one hand, and springs 42 and 421 on the other.

Supports 17 and 171 will be prevented from rocking, since the otherparallel supports 1S and 181 (Figs. l, la and 4) are locked by lockingmembers 53 and 531.

At the same time, cam 38 (Figs. 2 and 2a) will release lever 37, whichallows the movement of rod 36, lever mounted on shaft 34 and levers 33and 331, whereby bars 31 and 311 will slide towards the rear of themachine, under the action of springs 163.

Cross-bar 30 will also move backwards, this movement also affecting stopbars 2S and 281 by virtue of levers 25 and 251 exerting a pressure uponsalients 29 and 291 provided on said bars 2S and 281 (Figs. l and la).

Stop bars 2S and 231 are thus under the action of springs 164 and 1641,said springs 164 and 1641 pulling upon racks 22 and 221 (Figs. 8 and 20)by means of rollers 23 and 231 cooperating with rollers 24 and 241,provided on levers 25 and 251. It is possible, though, to stop thesemovements, by means of whichever key 931 to 93s has been depressed.

Racks 22 and 221 permanently -cooperate with pinions 21 and 211 in orderthat the rotation value of 'the pinion be proportional to the position,on the keyboard, of keys 931 to 939 which may be depressed by theoperator.

As described hereabove, pinions 21 and 211 are fast with shafts 16, 161carrying ngers 15 and 151.

The n ers are helically arranged on the shafts, so that each linger maybe opposite the triangle 13 which elongs to the counting unit, thenumeration order of which corresponds to that of lthe key depressed bythe operator.

The preparation for selecting the counting units is thus operated. Theunlocking of `slides 12 corresponding to said counting units, as well astheir engagement with driving and calculating means, will now bedescribed:

When shaft 39 continues its rotation (Fig. 6), cam 63 is rotated and thetooth 631 is engaged under the nose of lever arm 62, driving lever arm61 which, through roller 60 causes har 56 to slide towards the front ofthe machine, said bar 56 being at the same time under the action ofspring 58.

Bar 56 will simultaneously exert a pressure upon rollers 55 and 551,thus unlocking plates 1S and 131 through rotation of levers 53, 531(Figs. l, la and 4). At this moment, the unit composed of plates 17 and171, 18 and 181, and shafts 16 and 161 provided with ngers 15 and 151,will rock under the action of springs 42 and 421 (Fig. 3) and fingers 15and 151 which are opposite triangles 13 and 131 (Fig. 5) correspondingto the selected account, will exert a pressure on said triangles.

Bars 10 and 101 will slide, against the action of springs 64 and 641,thus releasing slides 12 from the locking bars 65 and 651 and engagingsaid slides 12 with driving and calculating means 98 and 961 (Figs. 5and 2 and 2a) hereafter described.

Cross bars 9 and 91 are provided with guides 101, 102 and 1011, 1021,inside which are slidably mounted driving bars 103 (Figs. 2 and 2a). Onsaid bars 103 are rotatively mounted triangular levers 104 and 1041(Figs. 1, la, 7 and 10) provided at the end of their horizontal armswith studs 105 and 1051, arranged for passing through an openingprovided in the driving bar 103 and to engage in grooves provided in thetransfer bars 106 and 1061 (Figs. 7 and 9) pertaining to the immediatelyinferior numeration order. Said transfer bars 106 and 1061 may slidealong guides 101 and 102 and are provided with slopes 100, arranged atan appropriate angle, for instance of 45 and which determine a parallelupward movement of the groove, when said bars are under the action ofsprings and 1101. On the end of the vertical arm of the triangularlevers 104 and 1041 are rotatably mounted ratchets 107 and 1071 andcounter ratchets 108 and 1081. The counter ratchets 108 and 1081 (Figs.2 and 2a) are provided with studs 109, 1091 entering grooves of theunratching bars 111 and 1111 (Fig. 1l). These unratching bars areprovided with slopes 100 identical to those of bars 106 and 1061hereabove mentioned, in order to determine a parallel upward movement ofsaid grooves when the unratching bars 111 and 1111 are under the actionof springs 112 and 1121.

lt should be noted that the amplitude of the upward movement of thegrooves provided in the slopes 106 and 1061 and 111 and 1111 is equal tothe pitch of stop bars 113 determined by the spacing of keys 114 and thespacing of the teeth of said stop bars 113, said pitch being also equalto that of the pitch of the slots arranged in slides 12 (Figs. 2 and2a). All unratching bars 111 and 1111 are provided with a salient 115cooperating with transfer bars 106-1061 also cooperating with a foot 116capable of engaging with the nose of a stop-member 117 in order thatsaid stop member 117 may lock the unratching bars 111 and 1111, thuslocking at the same time the transfer bars 106 and 1061, under theaction of two springs 110 and 1101 and k112 and 1121. Stop members 117are rotatively mounted on guides 101 and 1011 and are provided with agroove in which there engages a stud 11S arranged on va disengagingshaft 119 (Figs. 2, 2a, 5 and 7); this disengaging shaft 119 is mounted,on the one hand, on frame 1, and on the other on guiding plates 101 and1011, so that bearings 120 of slides 12 (Fig. 5) causes it to shift whensaid slides 12 reach their extreme position towards the front of themachine. Stop member 117 at the extreme right, as well as stop member11'] at the extreme left are provided with supplementary arms 121 and1211, connected together by a rod 122 (Fig. 7).

Transfer bars 106 and 1061 on the extreme right are not provided withunratching bars but are provided with a nose 123 the movement of whichis limited by stop member 117 on the extreme right. Consequently, when aslide 12 belonging to the highest numeration shaft (on the left) causesthe disengaging shaft 119 to shift in reaching its most forwardposition, unratching bars 111 and 1111 of said shaft and transfer bar106 and 1061 of the lowest shaft (on the right) are under the action ofthe right side of slides 12 when said slides are displaced from left toright under the action of the selecting and engagement members hereabovementioned. Said mobile angle members 98 and 981 are also provided withratchunder action of springs 135. While the machineV operatesits-cycle,'and during the rotation of shaft 39 and before stop bars havereturned to their extremeposition towards the front of the machine, theoperator may depress another key. Nothing wilLprevent said stop Vbars113 from returning, sincethe teeth of corresponding stop bar 113,

Y which must pass under the previously depressed rod 155,

ing fingers 126 and r12151 cooperating with ratchets 107, Y

1671V and counter ratchets 108 and 1G81 and also with stops'127, 1271,the operation of which will beV explainedk hereafter.

Springs 128`and 1281 are fixed, on the one hand, to .Y mobile anglemembers 93,931 by a hook 129, and, onV

the other, to the end of a rod 130 which is rotatively mounted on shaft131 of the ratchets and counter-ratchetsV 137 and 1071,' 108 and 1h81.Said rod is guided by a stud 132, entering a groove arranged in themobile angle members 98, 981 (Fig. 7). Rod 136 has for its only funcntion'to allow ends of springs 123 and 1231 to remain Yapart from oneanother, in order thattheyV should have a correct length.

Driving bars 163 which are to be seen in Figures 2 and 2a, are providedwith a salient 133, provided with a groove in which shaft 134 of stop`bars 113 is engaged 1 and said driving bars .11)3 are permanentlymaintained rearwards under the action of springs 135, one end of whichis hooked to a cross-bar 136 fast with a `support 1362 which isV fastwith plate 1. AV cross-shaft 137 is mounted on levers 138 fast withshaft 139 and Vis capable of rotating in bearings xed to plate 1. Alever140 is fast with shaft 139 and is connected through a rod 141 to alever 142. The lever 142 may also rotateYV around shaft 443 and isprovided at its end with an anti-friction will act upon said rod'bymeans of bevel 161 of rod 155 under the action of spring 157. Y

As soon as the tooth has gone by and Stop bars 113 are driven 'oycross-bar 137 to their extreme position, rods 155 will come downagainand will thereforey againV be ready to play their normal part of a stopfor the next operation. f Y On the vertical sides of the keyboardfframes 153 are rotatively mounted aps 336 to maintain rods 154 ina downward position in cooperation with inclined :planes 337, with whichrods 154 are provided. A cross-bar with large teeth 338 causes the flaps336 to Vtilt after each recording in order to release allrrods 154-whichhave been depressed by the operator. Tranverse movement of bar 338iscaused by cams and rods not represented in the drawings. Flaps`339 aremounted inthe same wayas aps 336,50 that whenany of arms 334 is broughtdown, aps 339 which correspond tosaid arm tiltover, thereby vdriving andtilting a zero nger 178 by means of stud 340 frame 63 and has for itsobjectk to limit upward an roller 143. Said roller 143 will or will notbeV under the Y action of cam 144 according to the rotation Vof shaft 39driving Vsaid cam 144. lf said roller 143 cooperates with cam 144, thewholeof the driving bars 103 is brought back Vto its normal position, i.e. to its yresting position towards the front of the machine, but if, onthe contrary, roller 143 and consequently, rod 141 are not under theaction of cam 144 driven by shaft 39, said bars 103 will be directlyunder the action of springs 135. Said driving bars 1113 are providedwith saw teeth 145 and a play compensating shaft 146 is rotativelymounted in supports 1462 solid with plate 1. On this shaft arerotatively mounted ratchets 147, one for each numeration order.: y

A lever 143 is solid with shaft 146 and said lever 148 (Figs. l and la)is connected through a rod 149 to a lever 159 rotatively mounted onshafted. Said lever 150 is provided with roller 151 which cooperates ornot with cam 152 whichfollows the rotating movement of shaft 39. ifroller 1 1, and therefore lever 151i cooperate with cam 152, ratchets147 will determine the correct'position of driving bars 163, which areactedvupon, on another hand, by springs 135.

Nine keys 114 (Figs. 2 and 2a) indicated by reference numerals 1141,11421143, 1144, 114.5, 114s, 1147, 114s, 114g are mounted on the upperpart of rods v154 sliding inside of frames 53, one frame being providedfor each numeration order (Figs. 2, 2a, 12, 13 and 2l). Thus, it may beseen that rods 155 are mounted parallel to rods 154 and are providedwith a stud 156, said Vstud passing through a slot and serving as ahooking point fora spring 157 hooked, at its other end, upon anotherstud 158 fast with-:rods 154.1; A spring 159 is hooked, at one of itsends, on to frame 153 and, at its other end, on to a studv 16d, which isalso fast with rod 154.

When the operator depresses a key 114, rod V154 fast K with said keyfollows the downward movement and spring downward movement of rods 144.

All the members which havebeen hereabove described ADDITroN Addition maybe simultaneously carried on in Va counting unit belonging to onesection Vand in another counting unit belonging to the other section ofthe machine. Y Y

Operator depresses keys 93corresponding to the counting unit number inVwhich the addition is desired, as well as keys-114 for the compositionof the amount toV beV added, thereby choosing the row which correspondsto the numeration order of eachY given figure. VOperator then acts uponthe control ofthe motor in order to start said motor, which'deterrninesa complete'revolution of shaft 39` as well as ofl all cams fast withsaid shaft, thus originating operations which will be describedhereunder. Y

For the sake of clearness the operator will be supposed to havedepressed keys 934vfor the front section and key 939 for therear'section, aswell as keys 1142, 1147 and 1145 respectively in thethree rows on the right of the keyboard, i. e. corresponding to theunits, tens and hundreds. Slides 12 belonging to the selected countingunit will also be supposed to be in the position indicated at 312 incounting unit No. 9V of rear section and at 128 in counting unit No;4.of the 'front section. All other slides of the two mentioned'countingunits are Vin a position which corresponds to zero, i. e. in theirextreme position towards the. rear of the machine, in coincidence withstop plates 162 and 1621 fixed on plate 1.

2a) which releases .lever 37, so that bars 31 (Figs. 1 ,and la and 2a-nd 2a) and their cross-bar 30, under the action of springs 163,release stop bars 91, 28 and 281 (Figs. l, la and 4). At this moment,stop bar 91 will be driven towards the rear of the machine under theaction of spring 84 (Figs. 4 and 20) and that of cooperating members 82,87 and 90. Since operator has not depressed any function key 92, stopbar V91 (Fig. 4) will slide freely until it has reached its extremeposition towards the rear of the machine and plate S2 provided withgroove 85 will also slide until it has reached its extreme positiontowards the right hand side of the machine, covering levers 73, 731, 74,741 and 75 which are thus maintained.

Simultaneously, stop bars 28 and 281 (Figs. 1 and la) will tend to slidetowards the rear of the machine under the action of springs 164 and 1641and that of levers and 251.

The operator having depressed keys 93A. and 939 of the front and rearsection of the machine, displacement of the stop bar 28 will be limitedby the rod of key 934 cooperating with tooth 165, while the rod of key939 cooperating with tooth 166 will oppose any further movement of saidstop 28 (Figs. 1 and la).

In these conditions, the disposition of the selecting members alreadymentioned, will bring about the cooperation of salients 29 and 291,engaging rollers 27 and 271 with levers 25 and 251 which, by means ofrollers 24 and 241 drive racks 22 and 221 and shafts 16 and 161 andlingers 15 and 151, so that, in the iront section of the machine, alinger 15 will be opposite triangle 13 corresponding to counting unitNo. 4, whereas in the rear section of the machine, a nger 15 will beopposite triangle 13 corresponding to counting unit No. 9.

Releasing of mobile ongle members and transfer sZopes.-As illustrated atFigures 2 and 2a and according to above indications, bars 31 areprovided with cross angle members 167 .and 1671 cooperating with anglemembers 98 and 981 provided with the ratching lingers 126 and 1261,which cooperate with ratchets 107 and 10,71 as above described. At theconsidered moment of the cycle of the machine, the mobile angle members93 drive the bars 31 towards the back of the machine.

The rearward movement of bars 31 causes a movement of slopes 168 and1681 (Figs. 1 and la) which liberate levers 169, 1691, 179 and 1761 thusallowing shafts 171, 1711 to rotate counterclockwise, driving therake-shaped members 172, said rotation being controlled by springs 173and 1731 (Figs. 9 and ll). Each tooth of the rakeshaped members 172 and1721 exerts a pressure on salient 115 or 1151 of a bar 111, 1111. Itwill be further explained that all bars 111 and 1111, as well astransfer bars 106 and 1661 will freely slide frontwards under the actionof the respective springs 110 and 1161 or 112 or 1121, as soon ascorresponding stop member 117 or 1171 has been withdrawn by releaseshaft 119.

Preparation of the engagement.-Together with the above-mentionedmovements, the preparation of engagement of account counting units isoperated in the following manner:

Cam 50 exerts a pressure on roller 49 (Fig. 3) which tilts lever 4S thencooperating with roller 47 in order to drive engagement bar 45, thuspulling springs 46 and 461 as well as springs 42 and 421.

Moreover, rollers 41 and 411, as well as plates 17 and 171, do notfollow this movement, since locking members 53 and 531, according to theabove explanation, maintain plates 18 and 181 (Figs. 1 and la), whichare fast with plates 17 and 171, in their locking position.

Second phase Function control.-Shart 39 continuing its rotation, cam 8l)(Fig. 4) engages roller 79, thus rocking lever 78 which was maintainedby spring 168.

Plate 81, in the at rest position of the machine plays the part of astop for levers 73, 74 and 75 and should normally release said leversunder the action of springs 76, but plate 82 having slid toits extremeposition, groove 85 of said plate 82 passes beyond the vertical plane oflever '75 and none of levers 73, 74 `and 75 will rise.

Consequently, plate 81 will pass over nose 185 of levers 73, 74 and 75without driving any of said levers.

Releasing of the correctorresimultaneously, cam '.152 (Figs. 1 and la)releases roller 151, thus causing levers 150 and 148 to rock, saidlevers being connected through rod 149 and being under the action ofsprings 335. Shaft 146 will follow this rocking and teeth 145 will ceaseto cooperate with the ratchets 147, cooperating with Vsaid shaft 146.

Third phase Positioning of adding sections- Shaft 39 continuing itsrotation, cam 144 (Figs. 2 and 2a) releases -lever 142, which drives rod141, said rod 141 releases lever 140 and allows shaft 139 to rotateunder the action of spring 174. Cross shaft 137 which, up to now,maintained driving bars 103, will revert backwards and its rearwardmovement will not be limited by angle-bar 167 since, according to theabove description of Phase l, said kangle-bar already was in a rearposition at the moment of the cycle described at Phase l. At this momentof operation of the machine, all driving bars 193 are released and areready to slide rearwards under the action of springs and .according tothe disposition of keys 1114 which have been depressed by the operator.

In the above example, the operator is supposed to have depressed key1145 in the row `at the extreme right, i. e. 'that of the units, key1147 in the immediate prior 'row corresponding to the tens and 1142 inthe next row, or row of hundreds; consequently, the iirst key rod of theunits will vstop the corresponding stop bar, as may be seen in Figures 2and 2a, through engagement of tooth 175, which progresses rearwards avalue equal to tivel pitches. The second key rod, that of the tens, willstop the corresponding stop bar through tooth 176, v'hich progressesseven pitches and the third key rod, that of the hundreds, will stopcorresponding stop bar 177, which progresses two pitches. None of theother stop bars will meanwhile have been able to progress, since zerongers 173 stop said stop bars by cooperating with teeth 179 of Asaidngers, if no rod has been depressed in the rows to which theycorrespond. Driving bars 103 are provided, as hereabove described, witha salient 133 which cooperates with shaft 134 on which are mounted stopbars 28, so that the rearward progression of driving bars 103 isdetermined by means of the stop bars, as has been described.

Fourth phase Action of the conectan-Rotation of shaft 39 Vcontinuing(Figs. l and la), cam 152 cooperates with roller 151 and under theeilort of its pressure, causes lever 150 to rock, which lever drives rod149 which will, in turn, cause lever 14S to rock. Shaft 146, on whichlever 148 is mounted, rotates clockwise and ratchets 147, which maybetter be seen in Figures 2 and 2a cooperating with said shaft, ashereabove described, insure, while at the same time correcting, thepositioning of driving bars 193, said positioning depending upon theprior phase and also upon which of the keys of the keyboard have beendepressed.

Engagement of the counting artnr-ln considering Fig. 5, it may be seenthat, immediately after the beginning of this fourth phase, tooth 631 ofcam 63 cooperates with the nose of arm 62 of engagement lever 61, thuscausing said lever to rock, which, in its turn, causes bar 56 to slidefrontwards. Said bar 56 exerting its weight both on rollers 55 and 551,causes the unit composed of levers 54 and 541, shafts 52 and y521, and.locking devices 53 and 531, to rock (Figs. 1, la and 4.),

and 1801 of bearings 18 and 181.

Resettz'ng of adding sections and disengagement of func-- ftions-Meanwhile, cam 144 (Figs. 2 and 2a) lhas reached `ja position whichcauses it to drive levers 142 and 140,

iingers 15.l Fingers (Fig. 20) corresponding'to countving unitvNo..4 inthe front section and to counting Vunit No. 9- in the rear section, willcooperate `with, noses 180 and 1801of triangles 13 and 131,respectively. As hereand 101, exerting on said bars a pushing movementwhich will result in disengaging all slides corresponding to countingunits No. 4 and No. 9 -froxn locking angle-bars V98 and 981 (saidangle-bars being better visible in Figs.

2, 2a and 5). It should be remarked that the locking device 53 and 531will lock in an` opposite direction, i. e.

in the engagement position of noses 181 and 1811 Yofv plates 18 and 181.

Fifth phase n Preparation of the dz'sengagement.-Conside1ing now 1 i2Y sL r inthelfollowing manner: if the above example is once moreVconsidered, the extreme right handside slide or units slideof countingunit No. 4, belonging to the front secfplates being accompanied by the;shafts 16 provided with above described, said triangles 13 and 131 willcooperate, VVatfthis moment, and only at this moment, with bars tion,was in position 8 and the return movement involved by drive bar has avalue of ve pitches.'

Consequently, notch 120 of said slide (Figs. 5 andj7) VWill have causedthe rockingV of disengaging shaftV 119,

which corresponds to the units, after a shifting of'two pitches, so thatVstud 118, fast with said shaft .Will'have caused stop member 117 torock and that unratchingllar 111 (Fig. 1l) correspondingv to the extremerightorder or units order, will no longer be stopped, eitherbyrst'opmember 117 which has rocked, nor by'rake-shaped inember v172 which hasalready `been withdrawn during the iirst phase. Consequently, spring 112will pull the'A unratching bar 111 and cause it to slide frontward's.VSaid Figure 3, after the end of thefourth phase,. shaft 39 .continuesto rotate, camV 50 releases roller 49, and, by

.means of the same connections as hereabove describedrbar 45. will beunlocked while slides43 and 431 will continue lto exert a pressure,under the action of springs 46 and 451, v 'upon rollers 41 and 411.However said pressure will not.V

cause the unit, composed of bearings 17 and 171, 18 and 181 to rock,since, as in the fourth phase,ithe lookingVV Y noses 180 devices 53 and531, Visible in Fig.. l, will lock connected by rod 141. Horizontalshaft .137 will bring back, frontwards, to their original -position,alldriving bars which have been displaced rearwards. All said bars Y `willtherefore have a return movement, the value of which will be exactlythat of the movement executed under the action of springs 135 duringPhase 3. This return movement, according to the above description, takesplace while slides 12 cooperate with mobile angle members 98 and 9.81

and according to the engaging functions as describedmin Y Phase 3.

Meanwhile, as above described, driving bars'103 cooperate with mobileangle members 98 and 981by means Aof the transfer members, i. e. therockable levers 104 Q i and 1041. Said levers are maintained in theirnormal axial position by studs'105 and 1051 entering into hori-f zontalgrooves arranged in transfer" bars 106L and 106i, and cooperate Withratchets 107 and 1071V andV counterratchets 108 and 1081.Counter-ratchets 1,08 `and 1081l are maintained in their'normal positionby means of Vstuds 109 and 1091 entering into thegrooves of theunratching bars 111 and 1111 and ratchets 107 and 1071 Yare maintainedin their ratching position through springs 182Y and 1831.

will follow the return movement of driving bars 103. Re- Y This explainsthe reason why slides 12 verting to the above example, the extreme righthand side slide of the counting unit No. 9, or units slide, belonging tothe rear section, and which was in positionr2'will pass on to position7. The immediately next slide or tens slide, which`was in position lwill pass on to position 8 and the following slide or hundreds slide,which was in position 3, will pass on to position ,5.

unratching bar 111 being provided with a slopedfsection edge, Vsuch asabove described, will drive counter-ratchets 108 through its horizontalgroove whichwill rise, as well as ratchet 107, and `will at the sametimerrelease mobile 'angle member 98. As soon as'mobile angle. memberr98is released, spring 128 (Fig.,7) acts upon said mobile angle member 98rearwards until edge 127 of saidV angle member" bears against the middleof counter-ratchet 108. As hasV been described, the position of saidedge 127 is such that the value of the rear movement is exactly equal toten pitches, the consequence of which will be that the slide will bedriven to its extreme rearward position; Meanwhile, driving bar 103 doesnot interrupt its movement and continues its return movement for theremainder of the ve pitches, that is threepitches, and, when driving bar103 corresponding to units, has attained its initial frontwards restingposition, the slide of the same numeration order will be in position 3.In'remernbering,` as hereabove described,rthat unratching bars 111 (Fig.7) are provided with a salient 115 (Fig. 7) to retain the transfer bar106 corresponding to the numeration order which isimmediately superior,it will be understood, in considering the same example, that unratchingbar 111 of the units, will have slid frontwards. Transfer bar'106,corresponding to tens, also under the action of spring 110, will' driveupwards stud 105 whichsisrfast with lever 104 corresponding to tens.Vcause mobile angle member 98 otY tens to move frontwards one pitch,this-value being in supplement to that determined by the return of thedriving bar of the tens. Still considering the proposed example, slide12 of teus of counting unit No. 4 belonging to the front section was inposition.2, the driving bar of the same order then operates a returnmovement of 7 and, as hereaboveide- 1 scribed, lever 104, belonging tosaid driving bar, shifts-and 12 causes unratching shaft 119 as wellasstop member of Slides 12 of counting unit No. 9, belonging to the rearY section, have thus operated the followingQaddition:

3l2-f-275=587. l

Itnmay however happen that the hereabove described return movementscause advancements of slides 12 which `are greater than the complementto 9 of the position (in number of pitches) which they-occupied at themoment of their engagement with levers 104 and 1041. 1n such a case, thedevices provided forthe transfer will operate tens 117 to rotate so thatthe unratching bar of the same numeration order Vwill risekand, duringsuch a rise, will exert an effort on ratchet 107 of tens, to raise saidratchet 107, thus releasing mobile angle` member 98 of the'same order,which, in turn, willrevertrearwards ten pitches in the same manner asthe units anglev member reverted, with .the diierence that in the casenow considered, the slide V12 will remain in its extreme rearwardposition. VAt the Sametime, transfer bar 106 corresponding to hundreds,being norlonger stopped by unratching bar 111 of tens, will also slideand will drive lever 104 ofV the driving vbar of hundreds, which, as inthe case of tens, will cause the mobile angle member 98 of hundreds tomove frontwards the supplementary pitch. Finally, slide 12 of hundredsof counting unit No. 4, belonging to the front section of the machine',was atV one pitch from its extreme position.

The'return movement of driving bar of the same order` has a value of twopitches and the supplementary advance,

Ratchet 107 will therefore,
